About This Tool

Why use this tool?

Serving a 4000px photo displayed at 800px wastes 25x the bandwidth. Resizing images to their actual display dimensions is one of the simplest, cheapest performance improvements for any website.

When should you use it?

Preparing images for social media exact sizes
Resizing profile photos to platform requirements
Reducing dimensions before emailing large photos
Fitting images to WordPress or Shopify layout requirements

How does it work?

ConvertPix uses the HTML5 Canvas API built into every modern browser to process your images entirely on your device. Your files are read from your local storage, processed in browser memory, and saved back to your downloads. They never travel over the internet — not even a single byte.

Is it free?

Yes — completely and permanently free with no limits, no watermarks, and no account needed. ConvertPix is supported by the display advertising you see on this page.
